Outdoor unit for air conditioner

Abstract

An outdoor unit for an air conditioner is provided, which includes a case, a plurality of path portions separated from each other in the case and having a same discharge port, electronic units arranged on the plurality of path portions, and an air circulator arranged on the discharge port of the plurality of path portions to compulsorily circulate air in the case to an outside of the case through the plurality of path portions of the case.

What is claimed is: 
     
       1. An outdoor unit for an air conditioner comprising:
 a case; 
 a plurality of paths formed in the case, the plurality of paths including a first path and a second path which is formed adjacent to the first path so that the first path and the second path is divided by a shared surface; 
 a first electronic component arranged in the shared surface so that a first part of the first electronic component is exposed in the first path and heat from the first part is dissipated by air flows through the first path and a second part of the first electronic component is exposed in the second path and heat from the second part is dissipated by the air flows through the second path; and 
 an air circulator arranged on a first discharge port of the first path to compulsorily circulate the air in the case to an outside of the case through the plurality of paths of the case. 
 
     
     
       2. The outdoor unit as claimed in  claim 1 , wherein the plurality of paths have intake ports formed in different locations. 
     
     
       3. The outdoor unit as claimed in  claim 2 , wherein one of the intake ports is formed at a lower part of the case, the first discharge port is formed at an upper part of the case, and the air circulator discharges air that flows into the lower part of the case to the upper part of the case through. 
     
     
       4. The outdoor unit as claimed in  claim 1 , wherein the case comprises a first duct which forms the first path and the air flowing through the first duct is discharged through the first discharge port and a second duct which forms the second path and the second path has a second discharge port which the air flowing through the second path is discharged therethrough. 
     
     
       5. The outdoor unit as claimed in  claim 4 , wherein the first path is arranged more adjacent to the air circulator than the second path. 
     
     
       6. The outdoor unit as claimed in  claim 4 , further comprising a second electronic component that is arranged in the second path, and the first electronic component is a heat generation body having a heat generation rate that is higher than the heat generation rate of the second component. 
     
     
       7. The outdoor unit as claimed in  claim 6 , wherein the first discharge port of the first path is formed on a downstream side of an air flow path of the first path so that the air flowing through the first path cools the first electronic component when passing by the first electronic component and is discharged through the first discharge port of the first path. 
     
     
       8. The outdoor unit as claimed in  claim 6 , wherein the second discharge port of the second path is formed on a downstream side of an air flow path of the second path so that the air flows through the first path cools the second component when passing by the second component and is discharged through the second discharge port of the second path. 
     
     
       9. The outdoor unit as claimed in  claim 1 , wherein the air circulator comprises a fan to force the air in the case to be discharged to the outside of the case. 
     
     
       10. An outdoor unit for an air conditioner comprising:
 a case; 
 a plurality of electronic components installed inside the case, the plurality of electronic components including a first electronic component; 
 an air circulator including a fan that forces internal air of the case to discharge to an outside of the case; 
 at least one intake port to introduce outside air into the case by the fan; 
 a discharge port where the air introduced through the intake port to be discharged to the outside of the case; 
 a first path formed in the case through which the air introduced into the case by the fan flows; and 
 a second path formed in the case and is adjacent to the first path so that the first path and the second path are divided by a shared surface, 
 wherein the first electronic component is installed in the shared surface so that a first part of the first electronic component is exposed in the first path and heat from the first part is dissipated by the air flows through the first path, and a second part of the first electronic component is exposed in the second path and heat from the second part is dissipated by the air flows through the second path. 
 
     
     
       11. The outdoor unit as claimed in  claim 10 , further comprising a duct which forms the first path, wherein the duct is configured to accommodate the first part of the first electronic component, and the duct has the intake port to introduce the air to cool the first part of the electronic components and the discharge port to discharge the air flowing inside the duct to the outside of the case. 
     
     
       12. The outdoor unit as claimed in  claim 11 , wherein the first path is arranged more adjacent to the air circulator than the second path. 
     
     
       13. The outdoor unit as claimed in  claim 12 , wherein the plurality of electronic components further comprises a second electronic component that is arranged on the second path. 
     
     
       14. The outdoor unit as claimed in  claim 13 , wherein the first electronic component is a heat generation body having a heat generation rate that is higher than the heat generation rate of the second component. 
     
     
       15. The outdoor unit as claimed in  claim 10 , wherein the intake port is located on a lower part of the case and the discharge port is located on an upper part the case so that air that flows introduced to the intake port by the fan moves from the lower part to the upper portion thereby passing through the plurality of electronic components to cool the plurality of the electronic components.
